Residual Feed Intake and Feed Efficiency: Differences and Implications
In the beef production system, 70-75% of the total dietary energy is used for maintenance (Ferrell and Jenkins 1984; NRC 1996; Montaldo-Bermudez et al. 1990). Thus, while only 5% of the total life cycle dietary energy consumption is used for protein deposition in beef cattle, swine and poultry are more efficient at 14 and 22%, respectively. The relatively large size, slow maturity and slow repr...
متن کاملEvaluating the Role of Corticotropin Receptors on Feed Intake Using Melanocortin Receptor Agonists in Neonatal Broilers
Evidence from animal studies suggests corticotrophin and melanocortin systems have regulatory role in feeding system in avian, but there is no evidence for their interaction. In this survey three experiments designed to investigate the role of corticotrophin receptors on food intake using melanocortin receptors agonist M3 and M4 in neonatal chicken (each experiment includes 4 groups and 11 bird...
متن کاملHow important is feed intake?
Over the past 10 to 15 years there have been very significant changes in pig performance due to selection. The result has been an increase in maximum protein deposition, a shift in the distribution of energy towards more protein and less lipid deposition, an increase in maintenance requirements and a decrease in voluntary feed intake (Knap, 2000). Using national UK data, Walters (2000) estimate...
متن کاملCASE STUDY: Feed Intake and Performance of Heifers Sired by High- or Low-Residual Feed Intake
The objective of this project was to investigate the effects of selecting sires for residual feed intake (RFI) on the performance of their daughters. Bulls with low or high estimated breeding values (EBV) for RFI were selected from the Angus Society of Australia sire summary and mated to Angus cross commercial cows at the Kansas State University Cow-Calf Unit in 2005 and 2006. The average EBV o...
متن کاملFeed Quality Quality control in feed manufacturing
FEED manufacturers are often forced by circumstances to focus on short-term concerns such as: How many tons were produced this week? How many customers do I have, or how much down time did I have this week? While important, short-term problems can cause manufacturers to focus on solving problems rather than pursuing the company’s mission. Manufacturers who regularly examine their company’s miss...
